I liked the concept, as it fits the theme so well, but the controls were so difficult. I found some of the jumps required spamming what I thought was the right combination of buttons until I executed the move I wanted to. I made it to the third level, but having to wait for the moving platforms to get into position, combined with the unforgiving controls, made me throw in the towel. Something I found particularly difficult was having both my movement and the direction of the projectile tied to the same direction control. For example, I'd jump to the left and up, and wanted to shoot down and right to boost myself in the same direction, but ended up just moving myself in the air. Having the bullet direction tied to where the mouse cursor is would provide much more intuitive controls I think, although would obviously require modifying the puzzles. Having time slow down while you were in the air would also help when trying to make particularly tricky jumps.
